Baja STI project complete, great results!!!

[wikidwrx]

Hi all, we'll it finally happened. Got my ECUtek re-flash/dyno tune today at Grouppe-S By Mike W. Dude's awesome. He dyno tuned the Baja and the end result is: 258WHP and 278WTQ @ 16PSI max on the Mustang Dyno (stock STI's registers at 205WHP - 210WHP).
So to sum it up, my upgrade is as follows Random tech exhaust, Helix up-pipe,
walbro 342 fuel pump, VF-39, STI TMIC and ECUtek reflash/dyno tune.
The baja now drives like a bat out of hell. The pull is smooth as butter. I've never seen my RPM needle sweep so quickly.

Again, props to Mike and Grouppe-S. Specailly Mike for working with the ECU tek peeps to develop the correct rom file for my Baja.

Here are pics from the dyno tuning:

Here's a vid clip of it. Select the Dyno tuning vid clip file.

Well, that is it folks. my HP gain expectancy was exceeded by 8WHP and the torque, it's unbelievable considering my stock figure is 180WHP/199WTQ.

Congrats, thats awesome!

[BajaNut]

nice. I whish I could afford to do that. Wikid, you need to join us some monday in Scotts valley.

Good stuff!

Would you consider your general setup to advance the Baja-T to stock STI specs or something thereabouts?

Now that you have the VF39, TMIC, ECU upgrade, and exhaust, would you have expected to get closer to 290whp?

[ez bturbo]

very sweet results!

[holland_patrick]

290 whp is crazy he would need to change to a front mounted IC those handle 300+hp which is what the crank would be putting out. I'm not sure what the loss is but let's say 10% it's now 260whp add another 26 on to that (use fuzzy math i'm working backwards here and trig was SOooo long ago) that 285 crank Hp that's 75 over what subbie states it is...

[Filanwizard]

so was the total out the door cost for this?

A Water/Methanol Injection Kit with his STi TMIC can handle 300whp.

Thanks! How's your boost issue? Anyway, I found out that my autometer boost gauge is off and it reads 1PSI more than actual. I will be switching to OMORI gauge soon.

I wish your meet was on a Saturday or Sunday. Kinda hard for me to go to meets on weekdays but I will surely be at the Mt. Hammy meet. LMK if you'll be there

Mike, the tuner at Grouppe-S, did an excellent job on the dyno tune. We have surpassed the STI spec given that a bone stock STI dynos at 205-210 WHP(I'm not sure about torque).
It's going to be hard to achieve that 290HP on my setup. There is only a little more room for improvement left like maybe adding headers but as it stands, I am very pleased with the results both on dyno and road. You'd have to test drive it to see or feel what I mean.

Haha. I'm not sure where you got the 10% but an example is that on the Mustang dyno a stock STI registers at 205 to 210 WHP. Well, lets use 210
for a best case scenario on a stock STI. That means the Baja makes 48 WHP (which is BTW 22.8%) more than the stock STI . How could I have 285 crank HP if a stock STI is 300 crank HP? Not out to get you or anything but I'm just trying to make some sense
To sum it up my baja crank HP is 300 +22.8% of 300 = ~370
Does that make sense?

TBE = 1400.00 + s/h
up-pipe = 179.00
Walbro pump = 100.00
VF-39 = 400.00
Sti TMIC = 350.00
ECUtek
and dyno tune = 700.00
Total = $3129.00 and ~80WHP gain

which is less of what I spent on my WRX with VF34, XEDE, TXS TMIC, STI injectors, Walbro pump, TXS TBE, TXS uppipe, dyno tune and only made 246WHP/236WTQ on vishnu's dyno.

You may be able to save some $ if you custom make a full 3" TBE (Keep in mind, you can use any WRX or STI Up-pipe and downpipe). I just got a real good deal on the STI TMIC and VF39.

Wikid, I don't think that I will make it to mt hammy, but we are planning on haveing a dirt drive or some tye of weekend run in the santa cruz mountians or something. I will keep you posted on what happens. We have too many people in school and in the same boat as me, just about flat broke.

About the math I'm not a number wizard and I didn't know the numbers that the stock sti comes with Sorry that is my fault and i was just gueesing at the loss beause I do know there is drive train loss.

[TurboBaja]

Hey Wikid,

That is Awesome! When I got the Baja in October, I promised myself I wasn't going to mod it... I got my up-pipe delivered from Gruppe-S on Saturday... I didn't get a chance to install it this weekend, but I am chompin' at the bit wanting to get it done.

[ez bturbo]

on a dyno jet, I believe the Sti dynos 220-225whp. Thats for 300 bhp rating, which is ~25% drivetrain loss. The WRX also supports those drivetrain loss numbers. So 258whp is around 345hp IF it were on a dynojet, but the mustang dynos are often lower, so it could be as you say if an STi does around 205whp on it, then you are about 20whp low, and your baja is in the 365 range.

I know the sti can support 17psi -- have you thought about trying one extra psi boost and see if that helps or hurts your numbers?

Either way awesome results.

PS my boost gauge still shows me max around 10.5 psi. Maybe ill bring it up next time cars at the dealer although im sure they wont be able to do much about it (or even care)

[02_Forester]

just watched the video clips -- awesome!!

Ok, kool. Lemme know if that is going to happen.

It's all good Bud. The power loss is around 25 - 30 percent and varies from baja to baja, dyno to dyno and also area conditions. No worries, I was just trying to explain how to figure it out

Yep, it'll be nice when you're done with the install.

I would like see 21psi on your set up with A Water/Methanol Injection Kit.

Nah! I'm happy with it for now plus boost means nothing or even dangerous if not tuned right or has internal engine mods. I'm not out to make crazy power
anyway just enough to hold my ground against unsuspecting ricers lol!

Yeah, I was thinking of checking in to the 'Henry Ford Clinic' for my addiction.

[02_Forester]

we should all admit ourselves at the same time so we can discuss future upgrades.

Yup, pass the wrench bro!

The KEY word is...
"I'm happy with it for (NOW)"

Did you see the PDX Tuning Dyno Sheets for the 05 Legacy GT Stage1 & 2 upgrades?
Your numbers are very close to there Stage2
http://www.pdxtuning.com/technical_legacy_stage1.htm
You got a more whp but the torque is right there.

I too, made a promise to my wife. I wasn't going to mod the New BAJA and void another warranty.

So, wikid,
Thank you for bringing me back to my senses.
I don't know what I was thinking, making a promise like that.
